Internal shocks model for microquasar jets (2008)
Jamil, Omar, Fender, Rob, Kaiser, Christian
We present an internal shocks model to investigate particle acceleration and radiation production in microquasar jets. The jet is modelled with discrete ejecta at various time intervals. These ejecta...
Searching for the signatures of jet-ISM interactions in X-ray binaries (2008)
Miller-Jones, James, Kaiser, Christian, Maccarone, Tom, Fender, Rob, Kapińska, Anna, Gunn, Katherine, ...
Jets from X-ray binaries are continuously injecting matter and energy into the surrounding interstellar medium (ISM). However, there exist to date relatively few cases where jet-ISM interactions have...
Heating rate profiles in clusters of galaxies (2007)
Pope, Edward, Kaiser, Christian, Pavlovski, Georgi, Fangohr, Hans
The results of hydrodynamic simulations of the Virgo and Perseus clusters suggest that thermal conduction is not responsible for the observed temperature and density profiles. As a result it seems...
Survival-Modelle in der betriebswirtschaftlichen Forschung - Grundidee, Methodik, Anwendungen (2007)
Erfolgsfaktoren organisatorischen Wandels (2007)
Markus Schwaninger, Christian Kaiser
Die empirische Forschung hat sich fast nicht mit der Frage nach den Erfolgsfaktoren von Projekten der organisatorischen Veränderung befasst. Um diese Lücke zu schliessen, wurde eine exploratorische...
Real time observation of TF function on translating ribosomes (2006)
Ribosome-associated Trigger factor (TF) is the first molecular chaperone to bind to nascent polypeptides in bacteria. The contribution of co-translational chaperone function is yet poorly understood....

Merge or Fail? The Determinants of Mergers and Bankruptcies in Switzerland (2006)
Stefan Bühler, Franz Jäger, Christian Kaiser
This paper examines the determinants of mergers and bankruptcies using firm level data from Switzerland. We find considerable differences in the determinants of mergers and bankruptcies. Our results...

The Semantic Web presents the vision of a distributed, dynamically growing knowledge base founded on formal logic. Common users, however, seem to have problems even with the simplest Boolean...
Competition Policy and Exit Rates: Evidence from Switzerland (2005)
Buehler, Stefan, Kaiser, Christian, Jaeger, Franz
This paper provides evidence on the relation between the intensity of product-market competition and the probability of exit. We adopt a natural experiment approach to analyze the impact of a...

Black hole X-ray binary jets (2005)
Gallo, Elena, Fender, Rob, Kaiser, Christian
Relativistic jets powered by stellar mass black holes in X-ray binaries appear to come in two types: steady outflows associated with hard X-ray states and large scale discrete ejections associated...
Everything for the Brand? Conflicts between Brand Conformity and Independent Product Lines (2005)

Letter to Nature: A dark jet dominates the power output of the stellar black hole Cygnus X-1 (2005)
Gallo, Elena, Fender, Rob, Kaiser, Christian, Russell, David, Morganti, Rafella, Oosterloo, Tom, ...
Black holes undergoing accretion are thought to emit the bulk of their power in the X-ray band by releasing the gravitational potential energy of the infalling matter1. At the same time, they are...

Novel materials for magnetic tunnel junctions (2004)
Die vorliegende Arbeit beschäftigt sich mit dem Tunneln von spinpolarisierten Elektronen in magnetischen Tunnelkontakten (MTJs). MTJs bestehen aus zwei ferromagnetischen Schichten, welche mit einer...
Bubble-heated cooling flows (2002)
Churazov, Eugene, Böhringer, Hans, Brüggen, Marcus, Forman, William, Jones, Christine, Kaiser, Christian, ...
Kaiser, Christian, Koehler, Kai
We give a new proof of the Jantzen sum formula for integral representations of Chevalley schemes over Spec Z. This is done by applying the fixed point formula of Lefschetz type in Arakelov geometry...

Suppression of Raf-1 kinase activity and MAP kinase signalling by RKIP (1999)
Yeung, Kam, Seitz, Thomas, Li, Shengfeng, Janosch, Petra, McFerran, Brian, Kaiser, Christian, ...
Raf-1 phosphorylates and activates MEK-1, a kinase that activates the extracellular signal regulated kinases (ERK). This kinase cascade controls the proliferation and differentiation of different...
